Dr. Vera Ribeiro, the wife of Portugal goalkeeper Rui Patricio, is advising all players at the World Cup - including her husband - to pleasure themselves regularly for the duration of Russia 2018.

Dr. Ribeiro, who is a qualified sex therapist, suggests that a team that regularly masturbates will have a better chance of success at this summer’s World Cup. She has recently published a book that examines the sex lives of professional footballers, which questions the generally accepted rule that having sex the night before a game can lead to a below-par performance on the field.

“Nothing positive can come from abstinence,” Dr. Ribeiro suggests in the book, also adding that coaches who forbid their players from sex before a game are doing more harm than good.

“The football player should not abstain from having sex before games, but we also know that in terms of routine they are not in contact with families either,” she claimed on Portuguese TV, according to as.com.

Whether or not her husband Rui Patricio has the will to take his wife’s advice remains to be seen, but if he does, we expect his hotel room to be among the most tranquil places in all of Russia this summer.
